In this country, many people have anthropomorphized animals due to movies like Bambi. In real life, animals are not like that. Look at the guy who went up to Alaska to be with his “friends,” the Grizzly bears.
Animals do feel pain, but they are incapable of using reason to fear pain and death. If an animal has fear issues, they are the same thing as Pavlov’s dogs’ responses to the bell–a learned response to a certain critera that has produced the same result time after time.
It is morally right to raise animals for their fur according to the Catechism of the Catholic Church, #2417 specifically says animals can be used for clothing. BUT it would not be right to abuse those animals. They need proper food, water, bedding, space, etc., all of which it is also to the advantage of the farmer to provide because he will end up with a better quality pelt in the end. It is not to the advantage of a farmer to mistreat or cause premature death in his animals by not taking proper care of them.
By the way, many times, the love for animals can take away from the love we should have for other human beings. It’s sort of like the Dulia/Hyperdulia veneration we should have for Mary vs the other saints. We can “love” our pets, but we are commanded by Our Lord to love one another and to take care of those who are in need of food, water, shelter, clothing etc. as if they were Our Lord himself.
